Overview
As part of the Space Operations Act (LOS), CNES is particularly interested in the atmospheric re-entry of space debris. CNES is responsible for ensuring the proper application of the law for each mission launched/operated from French territory.
PAMPERO is a multidisciplinary tool that models the complete atmospheric re-entry of a spacecraft. This includes the complex processes of thermo-mechanical fragmentation and ablation along a six-degree-of-freedom (DOF) trajectory.
